Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Nate Cole, Richard Zang, and
Xi Wang.


Bugs: AMBARI-13424
    https://issues.apache.org/jira/browse/AMBARI-13424


Repository: ambari


Description
-------

In some environments, the customer still wants to proceed with RU & EU even if PreChecks
fail. E.g.,
NameNode HA doesn't actually exist if they have their own distribution of HDFS
Hosts be down at the time the upgrade is starting, but will come online during the upgrade.

Today, they are unable to start RU/EU if any of the PreChecks fail.
Introduce a config in ambari.properties file called "stack.upgrade.bypass.prechecks" whose
default value is "false"
